JAR OR OTHER COVERED VESSEL.

SPECIFICATION forming part of Letters Patent No. 314.109, dated March17,1885.

I Application filed December 2, 1884. No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM H. CLARKE, a citizen of the United States,residing at Olean, Oattaraugus county, New York, have invented new anduseful Improvements in Jars and other Covered Vessels, of which thefollowing is a specification.

This invention has for its objects to provide novel and eflicient meansfor clampinga cover on a jar or other vessel; to provide a lever toclamp a cover on a jar, with two separated cam-bearings for acting onthe cover; to provide a cam-lever of such construction that when swungto clamp the cover in place the lever will embrace the bail or yoke towhich it is pivoted and thereby prevent the bail or yoke from beingforced sidewise; to provide means whereby a cam-lever disconnected fromthe cover to be clamped is prevented from moving sidewise on the coverwhen swung to clamp the latter on a jar or other vessel, and

to provide novel means for pivotally connecting a cam-lever with aswinging bail to clamp a cover in position on a vessel. These objects Iaccomplish in the manner hereinafter described and claimed, referencebeing made to the accompanying drawings illustrating my invention, inwhich- Figure 1 is a perspective view of the invention applied to afruit-jar, showing the camlever in its clamping position; Fig. 2, asimilar View showing the lever elevated to release the jar-cover, thejar being broken away;"" Fig. 3, detached views of the bail or yoke,camlever, and pivot-pin therefor; and Fig. 4, a vertical centralsectional view of the top portion of the jar on a reduced scale.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, where the number 1 indicates a jar such as is used for fruit;2, its covr resting on a rubber gasket; 3, a wire band encircling theneck of the jar, and 4 a yoke or bail pivotally connected or jointed atits two ends to the neckband.

The yoke or bail is bent midway of its ends into an eye, 5, which thusbecomes integral with the bail, and provides a simple and economicalprovision for engaging the pivot-pin 6 of the cam-lever 7. The lever ishollow to constitute two cheek-pieces, 8, substantially its entirelength, and the cheek-pieces directly opposite the pivot-pin are formedinto two cam-bearings, 9, which afford two distinct and separatedsurfaces to act on the cover and clamp it on the jar. The cheek-piecesand cam-bearings embrace the bail, and the pivotpin passes through thecheek-pieces and the eye in the bail, whereby these parts are pivotallyunited.

The cover is disconnected from the cam-lever and bail, and is centrallyprovided on its upper surface with one or more lugs or ribs, 10, whichare embraced by the cam-bearings when the lever is swung to clamp thecover in place, whereby the lever is effectually prevented from sidewisemovement when clamping the cover upon the jar.

The lever being hollow its entire length, or approximately so, willembrace and inclose the bail when swung down to secure the cover, andtherefore the bail is more effectually prevented from swinging or movingsidewise when the parts are in the locking position; and, further, thelever being pivoted to the bail by a transverse pivot-pin, is caused toswing in the longitudinal plane of the bail, so that sidewise pressureon the bail in no way tends to unclamp the lever, as is the case where acam-lever swings at right angles to the bail, as heretofore. if

By the construction shown and described a broad bearing on the cover isprovided, and the cover is therefore pressed evenly upon the jar tosecure a perfect and tight joint, and the cheek-pieces provide a greaterbearingsurface with less metal than a solid cam of the same size.

The invention is applicable to various constructions of jars, as well asto tubs and other vessels.

Having thus fully-described my invention, what I claim is-- 1. Thecombination of the swinging bail, the cam-lever embracing the bail, andprovided with two separated cam-bearings, and

pivoted to the bail to swing in the longitudinal plane thereof, thecover disconnected from the bail and lever, and the jar or vessel,substantially as described.

2. The combination of the swinging bail,

thereof, and the cover disconnected from the Y bail and lever,substantially as described.

4. The combination of the jar, the swing ing bail, the lever having twoseparated cambearings, and pivoted to the bail to swing in thelongitudinal plane thereof, and the cover having the central lug or ribwhich is em braced by the cam-bearings of the lever,- sub stantially asdescribed.

In testimony whereof I affix' my signature in presence of two witnesses.
